The probability that the first card drawn is a spade is 13/52. If a spade has been drawn on the first draw, there are 39 non-spade cards and a total of 51 cards remaining. Therefore the probability that the second card drawn is not a spade is 39/51.
The required probability is found as follows:
[tex]P(spade\ first+non-spade\ second)=\frac{13}{52}\times\frac{39}{51}=0.191
